Convert 62.0 °C to Fahrenheit
The Attempt at a Solution
°F=1.8(62.0) + 32 = 143.60
I am confused on the significant figures for the answer. Does the temperature equal 143.6°F because 32 is an exact number?
Or 144°F because 32 is not exact (part of temperature conversion formula)?
In the book (Chemistry Tro 6th edition) Exact numbers include "Integral numbers that are part of an equation" such as
radius =diameter/2, the number 2 is exact.
